Definitions
- the present invention relates to a wheel assembly having a frame and at least one set of wheels supporting said frame and including at least three wheels which are mounted on a holder equidistantly around the periphery thereof.
- the object of the present invention is to solve the above defined problem and provide a wheel assembly which permits, for instance, pulling a heavily loaded sack trolley provided with such a wheel assembly over a curb stone, up a staircase etc.
- This object is achieved in that the holder is rotatably mounted around the periphery of a circular bearing means whose centre axis coincides with the axis of rotation of the holder, and in that the frame is connected to the circular bearing means at a radial distance from said centre axis.
- FIG. 1 in side elevation shows a simple application of the invention.
- FIG. 2 shows a sack trolley provided with a wheel assembly of the type shown in FIG. 1.
- FIG. 3 shows a wheel assembly with driven wheels
- FIG. 4 is an end view of the wheel assembly in FIG. 3.
- the wheel assembly shown in FIG. 1 consists of a holder 10 in the form of an equilateral triangle. Adjacent the points of the holder 10, wheels 11 of equal size are mounted by means of journals 12.
- the holder 10 has a circular central opening in which a bearing means 13 in the form of a planar disc is mounted, for instance by means of flanges on the opposite sides of the disc which are of a diameter greater than that of the opening of the holder.
- the bearing means 13 can be provided with friction-reducing means, for instance in the form of ball bearings, around its peripheral surface facing the wall of the opening of the holder.
- the wheel assembly consisting of the holder 10 and the wheels 11 has an axial centre line on which the centre C of the bearing means 13 is situated.
- An axle 14 is fixedly connected to the bearing means 13 at a location spaced from the centre C of the bearing means.
- two wheel assemblies of the type shown in FIG. 1 can be mounted on a sack trolley by means of the axle 14.
- the trolley When the trolley is run and encounters for instance a curb, one wheel 11 of each assembly will strike the curb stone and the rolling movement will be stopped.
- the bearing means 13 Continued force exertion on the sack trolley will then cause the bearing means 13 to rotate as a result of the connection of the axle 14 with the bearing means at a distance from the centre C thereof.
- the means 13 will rotate clock-wise, resulting in a shifting of the line of force so as to increase the leverage, such that when the axle has rotated clock-wise slightly more than a quarter of a revolution, the holder 10 will start tilting to the left, whereby the topmost wheel 11 in FIG. 1 is pivoted downwards on to the top of the curb stone.
- the left-hand wheel in FIG. 1 will easily roll up on top of the curb and the continued movement of the trolley will take place with these two wheels rolling on the base.
- the right-hand wheel 11 in FIG. 1 will then be located above the other two wheels 11. It is evident that if, when running the trolley shown in FIG. 2, one encounters an obstacle which affects only one wheel assembly, this will mount the obstacle, while the other wheel assembly will continue its rectilinear movement.
- the three wheels 11 illustrated can be replaced by a single wheel, whose centre of rotation will then of course coincide with point C.
- more than three wheels 11 can be provided.
- the three wheels are mounted in the same plane but in a particularly suitable embodiment they are mounted in different planes, so that their peripheries will overlap as seen in the axial direction.
- the bearing means 13 need of course not be circular but may instead be in the form of an arm which is mounted in point C and, spaced therefrom, carries the axle 14 or the like.
- the embodiment according to FIG. 1 including three or more wheels is well suited for instance for sack trolleys or prams, while the embodiment including a single wheel is advantageous for instance in wheelbarrows.
- the holder 10 supporting the wheels 11 is provided with a bearing means 13a which can be mounted in the holder 10 in the same way as the means in FIG. 1 but which has an inner gear rim 16 integral therewith.
- the axle 14a is axially non-displaceably but rotatably mounted in the means 13a and carries a gear rim 17 which meshes with the inner gear rim 16 of the means 13a.
- the bearing means 13a will be rotated.
- a journal 18 which carries a gear wheel 19 (FIG.
- the invention provides an extremely simple wheel assembly which moves over all kinds of obstacles with facility.
- the size of the wheels 11 is of course selected according to the sizes of the obstacles to be expected when running the trolley on which the wheel assembly is to be mounted.
- a person can quite easily pull the sack trolley of FIG. 2 loaded with 100 kg up a staircase, which would not have been possible with a sack trolley of conventional design.
